MULTICOLOR STEREOSCOPIC DEVICE.

Specification of Letters Patent.-

Patented Oct. 15, 1918.

Application filed December 13, 1915. Serial No. 66,468.

To all whom it may concern:

Be it known that we, ALFRED ALLEN, JOHN J. MURPHY, and HARRY A. WILLARD,citizens of the United States of America, residing-atToledo, Lucascounty, Ohio, have invented new and useful Multicolor StereoscopicDevices, of which the following is a specification.

This invention relates to reproducing subjects as originally appearing.

This invention has utility when incorporated in views, and apparatus forfacilitating the inspection thereof, to disclose the third dimension inthe different colors thereof as a commercial proposition for compacthandling and shipment in little space at a minimum of expense forproduction, with simplicity for manipulation in use owing to absence ofinvolved or technical features.

Referring to the drawings:

Figure l is a perspective view of an embodiment of the invention, withparts broken away, shown in set up assembled position for use;

Fig. 2 is a front elevation of a stereoscopic View comprising colorvalue elements of dissimilar colors in fields of such colors, as adaptedfor use in the device of Fig. 1;

Fig. 3 is a perspective view in partially collapsed position of thefirst tube of the stereoscope device of Fig. 1;

Fig. his a perspective View in partially collapsed position of thesecond tube of the stereoscope of Fig. 1;

Fig. 5- is a perspective View in partially collapsed position of thethird tube of the stereoscope of Fig. 1; and

Fig. 6 is a side elevation of the pair of stereoscopic lenses formounting in the tube of Fig. 5.

The simplicity of thedevice is such that the elements thereof may beforwarded in knocked-down condition to the trade or users therebyminimizing space, with the device of light weight construction amplysubstantial .to withstand normal usage in practise.

The stereoscope comprises the main member 1, being a tube of rectangularcross section having the end closure 2 slightly offset by the coactingflanges 3,4, at the sides and .5 at the base to form a view receivingpocket when brought up to alined osition as to the tube 1, and. sofirmly hel by the locking ting off all light rays to a view placedagainst the end closure 2. v

The top portion has the window or cutback portion 8 approximatelybalancingthe light ray illumination of a view as tothe elements thereof,as inspected through the tube 1. This brings about a coiiperatingfunction in synthesizing or 'combining the value colors for accurate andeffectiveresults.

The element 9 (Fig. 6) may have openings therein surrounded by the'bentout wings 10 to whiclrmay be attached by an adhesive the respectivestereoscopic lens elements 11. This lens carrier 9 may be disposed tohave the lenses 11 register with the openings 12 in the collapsible tube13. Alining with the openings 12 are the openings 14 which in the set-upposition will have the wings 15 therefrom swung back into the tube andlockedin such partition forming position by the tongue 16 engaging therecess 17. The terminal flanges 18, 19, of the tube 13, are bent inwardto assist in the frictional holding of this tube 13 in tube 20 and alsolook carrier 9 in set up position. The tube 20 is thus held againstcollapse and is adjustable in the tube 1 for ready focusing of thelenses 11 as to the view in the seat 2.

This View may comprise the element 20 having'the color field 21, say ofred, with the outline 22 in said field valued in red. The correspondingstereoscopic element or view 23, from a spaced origin for stereoscopiceffectiveness, may have its field 24 of color dissimilar to the color21, say green, with the outline or image 25 valued in such color.

In the operation to attain the articles of manufacture hereunder, astereoscopic view ma pla t e, say of the Lumiere type. Owing to thedifferent speed actions of the complementary or differing colors, thissimultaneous be taken with any pan-chromatic the color green, developedfor proper strength relatively to the outline from the color red. Thesetwo separately produced outlines from the basic plate may be printed inadjacent positions for the regular stereoscopic view but each of theseoutlines 1n the projection of this stereoscoplc v 1ew, as an integralarticle of manufacture, is dlsposed in a field of its color.

'In the multiplication of these devices, they may beconvenientlyproduced as half tones, at a single impression completing each view, byusing say the red ink for the field and the outline, the strength of thefield differing so there is the outline contrast. While in otheroperations say as in printing from negatives, the field may be the stockcolor or the stock may be colored after the outline is developed thereonto produce a unitary article of manufacture. The result ing operativedevice or element is, whether or not the outline is of'black or of acolor, a color value outline in a field of such color. In practice, itis found the two colors mentioned are serviceable over a wide range foraccurate reproduction of multi-color work with different shades andcolorings be- ,vond the two in the viewas a result of inspection throughthe stereoscope herein, for there is a synthesizing or re-combiningapproaching original appearance in all the original tints, shades andcolors of the spectrum. The selection of the two field colors andcorresponding values simplifies this reproduction, not only forphotographic but for printing purposes. a

In some instances of special colored objects, it may be desirable tospecially adapt the contrast colors for the v1ew fields and the colorvalued outlines thereon. The instance herein of a strong color from oneend of the normalcolor spectrum, and a second strong color from theother region of the spectrum, due tothe color spacing, shows up in ameasure of practical commerclal worth, when combined for viewing in thestereoscope combination. In producing the views, the color 21 .may bethe color of the stock used or a coating on the stock, and outline 22may be in black ink thereon over or under a coating on the stock.Accordin ly, the single black outlines on the dissimilar for saidoutlines.

fields or backgrounds may at one printing impression produce a view ofspectrum disclosing effectiveness. This result from black ink is due tothe color valued black 2. A third dimension and color disclosing I viewcomprising two dis-similar color value outlmes and corresponding fieldsof color 3. A stereoscopic view including spaced origin color valuedoutlines, each having integral therewith a color valued. field of suchcolor. v

4:. A stereoscopic opaque picture comprising right and left hand viewshaving com. plementary color. values in fields of such color.

5. In a device for disclosing views in color by reflected light, thecombination with an opaque base of color outlines-thereon in fields ofcomplementary colors in union with said base.

6 In a device for disclosing more than two colors by reflected light inviews, the combination with an opaque base of complementary coloredfields thereon, each of sa d fields embodying an outline therein, sa1dcolored fields and outline being fixed with the base.

7. The combination in a picture disclosing field. I

8. The combination in a-picture disclosing dev ce, of a base providing acolored field fixed therewith and in said field an outline valued in thecolor of said field.

In witness whereof we afiix our signatures.
